Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
